Sound Science with a String and a Hanger

Blog Post

In this family STEM activity, students explore how sound waves travel. Do some materials transmit sound better than others? What Sound Does a Hanger Make? A pair of walkie talkies made with metal cans (or paper cups) and string can be surprisingly effective in transmitting sound across a long distance—more effective than just talking to someone across the same distance. But why? What do homemade walkie talkies do to sound? In this family science activity, students use simple… Read more

Sounds Like RFID: Using a Radio Frequency Identification (RFID) Reader to Make Musical Instruments

Science Fair Project Idea

Scientific Method

Passports, identification cards, bus passes, and even some credit cards contain RFID tags. An RFID (radio-frequency identification) tag allows a card to be read by a computer from a short distance away. While this is very useful in everyday life, would you believe you can make music with it? RFID + sampled music sounds + a little crafting = a fun musical instrument that is limited only by your imagination. In this science project, you will make handbells out of paper cups that play real sounds,… Read more

Have you ever helped your parents cook a pot of spaghetti? Strands of spaghetti are pretty long, so sometimes people break them in half so they fit into the pot more easily. How exactly does the spaghetti break? And what does this have to do with science? It turns out engineers and materials scientists study how materials break when they are bent. While professional engineers might be more concerned with steel beams in a bridge, you can still do a fun experiment with some pasta in your kitchen. Read more

Strength of an Egg: Weekly Science Project Idea and Home Science Activity Spotlight

Blog Post

In this week's spotlight: a materials science family experiment and science fair project that asks you to rethink what you know about eggs. Are they fragile? Or are they strong? If you've ever accidentally stuck your finger through one in the kitchen, you may think you know the answer! But the shape of an egg can support a surprising amount of mass.
